Answer:
sudden rapid melting of ice and snow
Explanation:
Most of the destruction at Kedarnath was caused by a sudden rapid melting of ice and snow on the Kedarnath Mountain, 6 km (3.7 mi) from the temple, which flooded the Chorabari Lake (upstream) and then Kedarnath. The temple was flooded with water resulting in several deaths due to drowning and panic-driven stampede.
